原始语种摘要: Abstract(#br)In this work, the mixed aqueous solutions of cationic surfactant – cetyltrimethyl ammonium chloride and non-ionic molecular polymer – polyacrylamide were tested to verify the speculation about their intensification possibilities of drag reduction performance. Sodium salicylate (NaSal) was used as the counter-ion salt. Six different combinations of mixed solution concentrations were tested at different temperatures ranging from 25°C to 50°C. Pure surfactant and polymer solutions were tested as control couples. It was found that the curves of mixed solutions could be divided into enhanced drag reduction zone, stable drag reduction zone and destroyed drag reduction zone. Surfactant molecules form micelles round polymer chains. Then the two...
